Change the rules and you may change the outcome. If we change from EC to the popular vote it changes A.) how the candidates campaign and B.) how the voters vote. Voters in deep red or deep blue states are discouraged to vote as we already know the outcome.
Going into this election neither candidate, nor the pundits on the tv, cared about the popular vote....it was all about the magic number of 270, which we heard for months and months that trump had no path to. Trump and Clinton knew the key states were FL, Ohio, Pa, Wisconsin and Michigan because they were the big swing states or light blue/red states. History and polls predicted Trump would not win them all, but the voters showed up and pushed the underdog over the edge.
If it were a popular vote, trump and Clinton would have campaigned in more areas, and more voters in other states would probably have voted. We will never know how that would have turned out.
Maybe Clinton would still have won the popular; maybe not.
And lastly, clinton won the national popular vote by 3 million because she won California by a whopping 4 million. I know Trump haters don’t like to talk about it but California has some pretty weak voter id laws, and quite a large number of illegals....
